SPRING-WHEEL.

Specification of Letters Patent. Patented Sept, 29, 1914. i

Application filed November 29,1913. Serial No. 803,764.

The invention relates to aspring wheel wherein the tire supporting rimis movably mounted with relationto the :hub and supported from thelatter by interposed spring members.

The main object of the present invention is the provision of a springwheel in which the tlre bearmg rim is connected to the hub by means ofspring members havmgremote yielding terminals connected respectively tothe hub and rim and an intermediate support fixed with relation to thehub, the terminals of the spring members projecting from a fixed supportof such member at op-' posing angles. 1

, The invention 1n its preferred form of details will be described inthe following specification, reference being had particularly to theaccompanying drawings, in which Figure 1 is a View in elevation of theimproved wheel, portions being broken away. Fig. 2 is a vertical centralsection of the same. Fig. 8 is a perspective of one of the springmembers. Fig. 4 is a vertical section of one of the hub plates. Fig. 5is a vertical section of the opposing hub plate. Fig. 6 is a verticalsection of one of the rim members. Fig. 7 is a vertical section of theopposing rim member.

Referring particularly to the accompanying drawings, the improved wheelc0mprises what I term hub plates 1 and 2, each including a circularplate section 3 and a hub extension 1 formed on the outer side thereof.The hub plate 1 is formed on the inner side of the plate section 3 witha sleeve projection 5 having the longitudinal opening 6 thereincoincident with the opening 7 in the hub portion. The sleeve extension 5is formed with spaced annular flanges 8, and the inner surface of themember 2 is formed with a depression 9 concentric with the'axle opening10 therein to receive the end of the sleeve extension when the parts arein connected relation. The members 1 and 2 are formed immediately beyondthe hub projection 4: thereof with an annular series of openings 11, fora purpose which will later appear.

The plate members 1 2 are held in connected hub formingrelation'by bolts12 passed through the alined openingsill of said members and securedbeyond the plate sections 3, securing the. members 1 and 2 to form acompleted hub 1 portion with the plates 3 thereof held in spacedparallel relat on and the respective flanges 8 equally such hubsections.

spaced from the adjacentinner surface of The rim memberoftheimprovedwheel 1 which is designed to be movably mounted wlth relation to the hubmember, comprises practlcally duplicate sections 13 and 14:, each ofwhich includes an annular plate 15 hav ing a laterally projecting flangeportion 16 arranged at right angles thereto at theinner circular edge.The two members 13 and-14c are so constructed that when associated inring forming relation, the flange 16 of the member 13 overlies and bearsupon the flange 16 of the member 14:, in which position theplatesections 15 are arranged in spaced parallel relation and have a maximumtransverse dimension corresponding approximately, to the transversedimension between the inner surfaces of the plate members 3 of the hubsection. The tread element of thewheel preferably comprises a series ofblocks 17 secured between the plate sections 15 of the respective rimmembers, the opposing surface of the respective blocks being on linesexactly radial of the wheel and said blocks being secured in place bybolts 18 passing through the plate portions 15, said plate portionsbeing if desired, formed with inwardly projecting spurs 19 to assist insecuring the blocks in place. The outer edges of the blocks arepreferably disposed with their grain ends outwardly, may if desired beprovided withan annular tread element or may be rounded as shown toprovide a tread element in themselves. As thus constructed, the rimmembers is mounted for free radial movement between the plates of thehub section, and as a connecting means, I employ spring elements 20comprising spring sections centrally coiled at 21 and having theterminals 22 projecting from the coils in relative angular relation. Thefree ends of the inner terminals of each spring member are bentlaterally and secured in openings 23 formed in one of the flanges 8, thecoils of the members being mounted upon the bolts 12. The free ends ofthe outer terminals of the spring members are bent laterally andsecured-in open-- ings 24 formed in,proj-eetions;25 extending inwardlyfrom the inner surface of the adjacent projections of the other row.

The construction insurest-hatin normal :'-posit-ion "the connections of"the respective terminals or iany spring meniberare in line. matiiallyof the Wheel, While *"the :mounting "OF that member,'that" is ithe boltI2, is 'o liset from such line..
